A further object of the invention is the provision of a lock of theabove specified type which will .be comparatively simple and inexpensiveto manufacture, reliable and efficient in use, and readily operated.

lVith the above and other objects in view, the present invention residesin the novel featuresof construction, formations, combinations andarrangement of parts to be hereinafter more fully described, claimed andillustrated in the accompanying drawin part of the present invention andin which Figure 1 is a perspective View of the invention showing thelock opened.

Fig. 2 is a plan view lookin at the inner side of the hasp.

Fig. dis a detail perspective view of the ke big. 4 is an edge view ofthe part shown in Fig. 2. a

Fig. 5 is a plan view of the lock removed from the hasp.

Referring now to the accompanying drawings by corresponding charactersof reference throughout the several views, the letter A represents aportion of a housing and B the closure thereof.

A plate 1 is secured to said housing and has a hasp 2 hinged thereon at3. A suitable fastening device 4 passes through an opening 4 provided inthe plate 1 and se cures the latter against displacement.

therein is indicated at 5. This keeper 5 is secured to the beforementioned closure B.

A hasp 2 is provided at its free end with an enlarged circular head 6,while lugs 7 extend from the inner side of the plate 1 holdmg the latteragainst rotation so that the head 6 will at all times be in alinementwith the keeper 5 and so that'the casing 8 carried by the head of thehasp will pass through the central opening provided in the keeper.

A flange 10 is formed at the outer end of the casing 8 and is secured tothe head 6 by suitable fastening devices such as the screws 11. r

Angularly disposedchannels 12 and 12 are provided in the casing 8 whileslidably disposed therein are looking bolts 13 and 13, which passthrough the sides of the casing through the openings 14 and 1 1.

The inner sides of the bolts 13 and 13 are provided with notches 15designed to engage the opposite edges of the key 16 so that uponrotation of the key in opposite direction the bolts will be projectedthrough the walls of the casing 8 and into engagement with the heldfirmly in engagement with the bolts by virtue of the engagement of thepin 17 in the opening 17 formed in the casing 8.

A suitable key opening 18 is provided in the hasp 2 in order that accessmay be had to the grooves 16 in the locking bolts, while in order tofacilitate the operation of the key 16 a suitable headl9is providedthereon.

From the foregoing description taken in connection with the accompanyingdrawings it will be manifest that a lock is provided. which will fulfilall of the necessary requirements of such a device, and it should beunderstood in this connection, that various minor changes in thespecific details of Having thus fully described the invention, what Iclaim as new and desire to protect by Letters Patent is In a hasplock'of the character described, the combination with a plate adapted tobe secured to a housing and having a central opening for the passage ofa fastening means, of a hasp hingedly connected'to said plate, having anenlarged substantially circularb d a d a ke pe with a flanged msingcarried by said head and provided with angularly disposed channels andhaving a central opening adapted to be engaged by the end pin of a key,notched locking bolts siidably disposed in said channels and passingthrough the sides of said casing, the

notches of said locking bolts adapted to be engaged by the oppositeedges of a key upon the rotation thereof for projeetingsaid bolts inopposite directions through the Walls of 10 said easing into engagementwith the keeper.

In testimony whereof I have afiixed my signature.
